Question

(3) In the following circle and rectangle, when AB (the length of segment AB) is 3, BC is 3, and DE is 2.5, find the length of EF.

Thank You!

Answer 1

I think that the length of DE is 4.  you can add 0.5 to each side of BC in order to find the length of EF since EF starts 0.5 before BC does and therefore also ends 0.5 after BC since the circle is symmetrical.
